Cementos Moctezuma has commissioned Loesche for a vertical roller grinding mill for its Apazapan plant expansion project, scheduled for the fourth quarter of 2016.
The Loesche vertical roller grinding mill LM 53.3+3 C will produce 205 tph CPC 30 cement at 4,000 Blaine as well as 195 tph CPC 40 cement at 3,700 Blaine. Loesche will also deliver a LDC classifier (Loesche Dynamic Classifier), as well as a COPE gearbox, including gearbox drive motors, developed in cooperation with RENK AG.
At the motor end, the innovative COPE gearbox features a redundancy of 8 motors. With all 8 motors in operation, an output totaling 4.6 MW is achieved. The customer advantage lies in the fact that the COPE gearbox can reach up to 100 percent of the mill capacity performance even with a reduced number of motors. The COPE gearbox has the same external dimensions as a conventional planetary gear system and thus requires no extensive enlargement of the mill foundations.
Cementos Moctezuma is a joint venture company of Cementos Molins, Buzzi Unicem and Grupo Carso.
